Ear pain, also known as earache or otalgia, is pain in the ear. [1] [2] Primary ear pain is pain that originates from the ear.

Hypoalgesia occurs when nociceptive (painful) stimuli are interrupted or decreased somewhere along the path between the input (nociceptors), and the places where they are processed and recognized as pain in the conscious mind. Hypoalgesic effects can be mild, such as massaging a stubbed toe to make it hurt less or taking aspirin to decrease a ...

[2] [3] Neuropathic pain may be associated with abnormal sensations called dysesthesia or pain from normally non-painful stimuli . It may have continuous and/or episodic components. The latter resemble stabbings or electric shocks.
The dorsal root ganglion contains cell bodies for sensory nerves including large, myelinated Aβ fibers which carry proprioception and tactile touch sensation to the brain via the dorsal column–medial lemniscus pathway and small, unmyelinated C fibers which carry thermal and pain sensation to the brain via the spinothalamic tract.

Sometimes pain arises in the absence of any detectable stimulus, damage or disease. [3] Pain is the most common reason for physician consultation in most developed countries.
